In a book printed by Solesmes Abbey in 1902, “Kyrie Rex Genitor” is also called Theoricam practicamque. Can anyone explain why?
And how does that translate into English? “Theoricam practicamque vitam regens Deus Pater.”
Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”
